WILSON EXT TUBE 1-SHOT 12GA RH BLK

Description

The Wilson Combat magazine tube extension for the Remington 870, 1100, and 1187 is a straightforward capacity upgrade aimed at shooters who want one more round on tap without adding significant length or weight to the platform. It threads onto the existing magazine tube in place of the factory end cap, so installation requires no permanent modification to the receiver or barrel.

This variant is configured for right-hand shooters: the integrated sling mount positions on the left side of the tube, keeping the attachment point clear of the operating hand and out of the way during manipulation. That placement is a deliberate ergonomic choice rather than an afterthought, and it matters during a fast reload or when transitioning between positions.

The tube is machined from aluminum and steel and finished in Parkerized matte black, which resists corrosion and reduces surface reflection without adding appreciable weight. Inside, a high-visibility follower gives a quick visual and tactile indication when the magazine is empty, and an extra-power spring is included to promote consistent shell feeding under the increased column load the extension creates. A wave washer is also included to maintain proper tension at the tube junction. One fit note worth knowing: the follower is not grooved for the detent found in newer 870 magazine tubes, so owners of current-production 870s may need to file down that detent for proper function.

Wilson Combat supplies these extensions to professional users who require reliable feeding under hard use, which reflects the standard of component selection and machining tolerance built into the design rather than a marketing claim.
